Yes i have tried that. No luck there! Thanks though!

Hi guys. i was amassed to find people that actually do what you do!! I was Googling for this inverter communication protocol when i saw your forum and now i have a hope that i might can get some help. I convinced my son to buy the Goodwe 5048ES because of the 5Kw backup capacity it has. I ordered from China a LiFePo4 batterie bank in the form of Four 10Kh batteries From Felicity Solar. (Model 48200) I installed them in parallel and i have a 40Kh bank at48v nominal. The problem is that the inverter is not recognize the BMS of the batteries and there is no communication happening. When i go to the App i self define the battery but the discharge depth is 60% Max. That means the 40% is been never used and the inverter is turning to the grid starts importing power. I contacted the supplier to find a solution to this only to find out that they need to have the communication protocol the inverter is using. Goodwe is not willing to hand out any info when i called them. I hope that someone here can help. My knowledge in electronics is nil.
